Saundra experimented with making solutions from water and a powdered drink mix. She measured the powder in tablespoons (T) and the water in milliliters (mL). She observed the color and taste of each solution and recorded her data in the table below. Water (mL) Powder (T) Taste Color
100 mL 1 weak
100 mL 2 normal
100 mL 3 strong
100 mL 4 very strong

According to Saundra's table, how did she make her solution more concentrated?

What is the molarity of the solution produced when 145 g of nacl is dissolved in sufficient water to prepare 2.75 l of solution?

Which states of matter have particles that move independently of one another with very little attraction?

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .
